R can't resolved error ?! Android Error

I rather intellij-Idea, it's fairly more stable than eclipse, but it requires an a little more advanced user.

Java packages, projects, etc are tied up to directories, files, sometimes something changes, a path, or the way the ide scans the dir and your project goes awol. It happens less in IntelliJ than in Eclipse.

Still, one thing that could have happened is you updated (or it auto updated) eclipse or java or android sdk, some path changed, some config was lost and your project lost a link to a jar file, a sdk or the path for something.

That is why usually re scan makes the trick, as it did your re install.

Sorry but I have a silly question ;

can I open my project in intellij-Idea though I used the Eclipse to develop at the begining ?!

So changing the paths again to defult can solved the problem?!

How can I do that ?!

sorry for annoying but I have to summit my work to the tutor this wensday.

Nothing to be sorry about, if anyone it would be Eclipse who should be apologizing.

Yes, you can work with eclipse projects on intellij this way:

Go to create project, fill whatever field you got, then in one of the next> it gives the option: Create from existing folder, there select your eclipse project folder and then it will ask you if you want to import the project
